Other books: The Definitive Guide to Drupal 7 is definitive because it covers code, configuration, and community— and always with an eye how to keep learning. We wouldn't be definitive on Drupal if we did not help pick out the best books from the plethora, and in that spirit, we will recommend other books as we come across them.

Drupal 7: the Essentials by Johan Falk and published by NodeOne covers Panels and other parts of the Drupal ecosystem given relatively short treatment in the Definitive Guide to Drupal 7.

Pro Drupal 7 for Windows Developers by Brian E. Travis, who did the Windows development environment appendix for DGD7, is an excellent introduction to theming and much more about Drupal regardless of the operating system you use— this book is about much more than Windows.
